Changes in Soil Biological Properties after Sewage Sludge and Pesticide Application in Wheat Cultivation

One of the solutions implemented in order to improve quality soils exposed pesticides is application sewage sludge, which a by-product wastewater treatment. As an organic substrate, it provides soil with important nutrients, such as nitrogen and phosphorus, enriches matter, thanks can be valuable fertilizer. The aim presented research was evaluate influence granulated sludge (GSS) on biological properties treated herbicides (MCPA dicamba) fungicides (thiophanate-methyl azoxystrobin). following aspects were investigated: activity selected enzymes, genetic biodiversity bacteria fungi, abundance bacterial gene responsible for ammonia oxidation. A field experiment conducted, applied at single dose 3 t/ha. Wheat (Triticum aestivum L.) sown prepared plots. (H) (F) well their mixture (F + H) plants appropriate growth phases doses recommended by producer. control without (C). samples taken tested for: dehydrogenases, catalases urease activities, structure fungi TRFLP assay, amoA qPCR. On basis obtained results, found that fertilized influenced enzymatic soil, differed depending enzyme. URE DHA plots GSS higher approx. 20% 30%, respectively, compared application. Moreover, both microorganisms variant experiment. treatment significantly studied C, its 9.15 log10 copies/g DW soil. Due content nutrients fertilizer agricultural crops pesticides.
